West Coast University Lab Assistant interview questions

I got there a few munites after ten and told the receptionist that I have an interview today with the dean and the chair of the campus. 30 minutes passed and I was still waiting. I asked the receptionist again if they were busy or running last and how much time they would be but all she answered to me was "oh they're just having a delay". So I waited for another 45 minutes and just left. I bet if I had stayed there I would have been all day waiting for the interview. I wish they could have just told me would you like to reschedule the interview. I have been to other interviews where the HR is ready to ask questions right when I would walk in and I would leave right away. If anyone wants to waste time this is the place and they don't care. It felt like the DMV.
